if your talking about the adjusting cone on the non-drive side of the rear wheel coming loose i'd like to say yes. Easton is sending me the adjusting nut that is slotted for a wrench. hopefully it will alow me to lock it against the outer end cap. Contact Easton if your wheelset doesn't have it and they will send you one. Similar to what American Classic hubs does. Hold the inside nut and back the outside nut against it, locking it in place.
